To help students understand number patterns and sequences through an interactive and visual working model. This DIY TLM model allows learners to predict the next number in a series and understand the logic behind arithmetic or geometric sequences.
Materials Required:
- Cardboard (base and stand)
- Chart paper or colored paper
- Number cards (0–100) or rotating wheels
- Paper strips/sliders with blank boxes
- Velcro or clips (to attach numbers)
- Sketch pens, markers, ruler, glue
- Optional: Rotating disc, flaps, sliders, or spinner for random pattern generator
How to Make – Step-by-Step:
Model Version 1: Number Slider
- Create a horizontal strip with 5–6 blank boxes.
- Provide sets of number cards to slide or place in order.
- Write down different number series patterns (e.g. +2, ×3, -5).
- Students place correct numbers in sequence to complete the pattern.
Model Version 2: Rotating Wheel
- Create a rotating wheel with number series logic in the center.
- Around the wheel, have numbers like: 2, 4, 6, 8, ?
- The wheel can spin and reveal the next number based on logic.
Types of Series to Include:
- Arithmetic Series (e.g., +2, +5, -3)
- Geometric Series (e.g., ×2, ÷2)
- Mixed Operations (e.g., +1, ×2, +1…)
- Squares & Cubes (e.g., 1², 2², 3²…)
- Fibonacci Sequence (e.g., 0,1,1,2,3,5…)
Educational Value (TLM Benefits):
- Develops logical thinking and pattern recognition
- Strengthens mental math skills
- Visual and tactile way to learn math
- Encourages active participation and interactive learning
